Definitions
- the present invention relates to a fire extinguisher for closed spaces.
- halon which from the fire extinguisher is supplied to the closed space and displaces the oxygen therefrom so that a rapid and effective fire extinguishing is obtained also in respect of fires in oil, petrol, solvents and electric systems.
- Fire extinguishers working with halon are extremely effective for extinguishing fires in closed spaces, such as in the motor space of vehicles and boats. Especially in racing cars the use of fire extinguishers working with halon has found an extended use.
- a drawback of fire extinguishers working with halon is the fact that halon destroys the ozone layer of the earth. It has therefore been decided on an international basis that the use of fire extinguishers working with halon shall be terminated within the next few years.
- the object of the invention is to provide a fire extinguisher for closed spaces having the same good properties as a fire ex- tinguisher working with halon without causing the risk for dam ⁇ ages to the environment and persons, provided by the use of ha ⁇ lon.
- the fire extinguisher ac- cording to the invention is characterized by a pressure con ⁇ tainer having a release valve and containing in association with the release valve a extinguishant liquid, the container having at the opposite side from the extinguishant liquid in relation to the release valve a pressurized driving gas for discharging the extinguishant liquid from the pressure con ⁇ tainer at a high pressure when the release valve is activated, and by at least one nozzle connected with the release valve for atomizing the extinguishant liquid supplied to the nozzle from the release valve at a high pressure for creating a liquid fog filling up the closed space.
- the liquid fog created by the fire extinguisher according to the invention is capable of filling up a closed space in which a fire has broken out and to displace the oxygen in the space, the liquid fog having at the same time a cooling action.
- the fire bro ⁇ ken out in the closed space is extinguished also in the case that extremely flammable materials, such as oil, petrol, sol ⁇ vents and the like have caught fire.
- the extinguishant liquid is constituted by water, the fire extinguisher creating when it is activated a liquid fog consisting of water.
- the use of water has the advan ⁇ tage that the water is friendly to the environments, unhar ful to people and animals and cheap. It is possible to add to the water an agent reducing the surface tension, for example a ten- side, which provides for a further improvement of the effi ⁇ ciency of the extinguishing action and obstruct re-ignition.
- the pressure container of the fire extinguisher com ⁇ prises two chambers separated from each other by means of a displaceable wall, one of the chambers being positioned in con ⁇ nection with the release valve and containing the extinguishant liquid and the other chamber containing the pressurized driving gas, the pressurized driving gas driving out the extinguishant liquid through the release valve by displacement of the move- able wall into the first chamber at a high pressure when the release valve is activated.
- a fire extinguisher designed in this way according to the invention discharges its whole amount of extinguishant liquid independent of the position of the fire extinguisher.
- the displaceable wall separating the chamber containing extin ⁇ guishant liquid from the chamber containing pressurized driving gas can be constituted by a piston which is displaceably ar- ranged in the pressure container but can also be constituted by a diaphragm.
- the diaphragm can be formed as a bladder constituting the chamber which contains the pressurized driving gas.
- the fire extinguisher according to the invention can also be designed so that the pressure container of the fire extin ⁇ guisher comprises two chambers for extinguishant liquid each provided with one release valve and a chamber for the pressur ⁇ ized driving gas, positioned between these chambers and sepa- rated therefrom by means of displaceable walls, wherein it is possible to supply the two chambers for extinguishant liquid with different amounts of extinguishant liquid with regard to the size of the closed space, with which the different chambers are connected.
- the extinguishant liquid is at the activation of the fire extinguisher atomized to a liquid fog having a droplet size of 15 - 80 ⁇ m.
- a droplet size of this magnitude it is necessary that the extinguishant liquid and the pressurized driving gas have during the emptying phase an aver ⁇ age pressure of 70 bar which means that the charging pressure prior to the activation of the release valve must amount to about 100 bar.
- a release valve which fulfills these requirements co - prises a discharge opening which is closed by means of a dia ⁇ phragm supported by a displaceable support element at the oppo ⁇ site side from the chamber for extinguishant liquid, the sup ⁇ port element being adapted at the activation of the release valve to be displaced from the position supporting the dia- phragm and the diaphragm being adapted in the position in which it is not supported by the support element to be ruptured by the pressure of the extinguishant liquid, whereupon the extin ⁇ guishant liquid is discharged from the pressure container through the discharge opening of the release valve.
- the support element of the release valve can be constituted by a piston which is displaceably journalled in the release valve and which by means of an end surface contacts the diaphragm in the position in which it supports the diaphragm.

- the chambers 20 and 22 are separated from each other by means of a piston 26 displaceably arranged in the pressure con ⁇ tainer and sealed with regard to the cylindrical wall 10 by means of sealing rings 24.
- the fire extinguisher has a fastening device 28 which is con ⁇ nected with the pressure container 2 and which can be con ⁇ structed with regard to the intended use of the fire extin ⁇ guisher and is therefore not described in detail.
- the end wall 12 is provided with a charging valve 30 for driv ⁇ ing gas, while the end wall 18 is provided with a charging valve 32 for extinguishant liquid and is in addition thereto provided with a pressure gauge 34 showing the pressure in the pressure container 2.
- the extinguishant liquid in the chamber 20 substantially con ⁇ sists of water possibly with the addition of a tenside lowering the surface tension of the water for giving a sticky covering surface on burning materials or objects according to the same principles as in foam extinguishing.
- the foam efficiently pre ⁇ vent re-ignition. It is also possible to add to the water an emulsion providing that the water is at the extinguishing of a fire in a burning liquid mixed with the liquid thereby prevent ⁇ ing re-ignition.
- the driving gas in the chamber 22 is consti- tuted by nitrogen, but it is of course possible to use any other suitable gas as a driving gas.
- the fire extinguisher is suitably charged to a pressure of at least 100 bar by initially supplying driving gas through the charging valve 30 to a pressure of about 20 bar, the piston 26 thereby being displaced to a position adjacent to the end wall 18 and the gas filling the whole pressure container, whereupon extinguishant liquid is supplied through the charging valve 32 until the pressure in the pressure container has reached at least about 100 bar, when the piston 26 has been displaced to the position shown in Fig. 1 and the driving gas has conse ⁇ quently been compressed in the chamber 22.
- the fire extinguisher contains 80% extinguishant liquid and 20% driving gas, counted on the volume.
- the fire extinguisher has the appearance shown in Fig. 1.
- the release valve 4 which is shown on an enlarged scale in Fig. 3 has a valve body 38 connected with an outlet opening 36 in the end wall 18 and screwed into the end wall 18. Between an inner end surface of the valve body 38 and an opposite surface of the end wall there is tensioned a diaphragm 40 of a soft ma ⁇ terial, for example rubber or plastic, which possibly can be reinforced in any suitable way and is adapted to close the out ⁇ let opening 36.
- the diaphragm 40 is supported at its side oppo ⁇ site from the chamber 2 by means of a piston 42 displaceably journalled in the valve body 38 and engaging the diaphragm with an end surface 44.
